    Yesterday,my 3ds started a problem. When I tried to turn it on, the blue light would turn on,but it would have a black screen. Sometimes, it shows a message that says "An error occured : Failed to mount CTRNAND FIRM". I was wondering if maybe someone could help me with this problem? I am running A9LH.

    If you have a NAND backup, you can restore it using GodMode9. Alternatively, you could try recovery mode: hold L+R+A+Up (D-Pad) and turn it on.
    I'd also recommend updating from A9LH to Boot9Strap, though this won't fix your problem; it's just a newer "hax." Many others will probably suggest the same, as well.
